We are going to put up an interior wall to create an additional bedroom, and we would like some sound insulation for the adjacent room. It doesn't need to be completely soundproof, but at least okay.
Planning to use double plasterboard with insulation boards in between and a solid door, but the problem is:
The ceiling is wood paneling with "grooves" running parallel to where the ceiling rail should be attached, see the image where the red line is where the ceiling rail will go:
What do you do here? Seal with some form of caulk in the grooves under the rail?
Well, it depends a bit on how much work you want to put in, but regular cheap latex caulking/painting caulk works well for soundproofing. It would be even better, of course, if you cut the ceiling on both sides and connected the ceiling directly to the construction, but that might be overkill.
I had set the rails against the panel, then mounted double boards, 2x plasterboard, or OSB + plasterboard, but with a little air between the board/ceiling board/wall etc., not in direct contact with the boards. Then seal. On the floor where I'm listing anyway, I have used flex foam, as it goes quickly and is durable, and also fills larger gaps (e.g., illbruck FM330). Considering the panel, you're probably putting up a ceiling molding too, so that works as well. Otherwise, a good seal.

Then seal. On floors where I still list, I have used flex foam, because it is fast and lasts long, and it also fills larger gaps (e.g., illbruck FM330).

Yes, I'll use ceiling molding, so maybe I'll just go with that. I'll probably need to seal around the door frame too, so maybe it works there as well? I'm thinking of using double plasterboard, should be okay. Thanks for the answers! I'll buy FM330 right away. I have some cheap latex caulk at home, but I'm not sure how good it is.

I'm planning to go with double drywall, so it should be okay. Thanks for the answers! I'll buy FM330 right away. I have some cheap latex sealant at home, but not sure how good it is.
I'm going to install crown molding, so I might just do that. I'll probably need to seal around the door frame as well, so that might work there too. I'm planning on using double gypsum, so it should be okay. Thanks for the answers! I'll buy FM330 right away. I have some cheap latex sealant at home, but I'm not sure how good it is.
All the frames I wanted soundproof, I've used FM330 foam. Maybe overkill, but it works. Then I buy soundproof frames for the doors. I go with compact (chipboard filled) or solid. Almost as good as a sound-rated interior door but much cheaper. I usually shop at mindorr.se
